GANT-HOOK.

SPECIFICATION forming part of Letters Patent No. 249,682, dated November15, 1881.

Application filed July 16,1881. (No model.)

To all whom it may concern:

Be it known that 'I, ALBERT Samoan, of Oshkosh, in the county ofWinnebago and State of IVisoonsin, have invented certain new and usefulImprovements in Cant-Hooks; and

I do hereby declare the following to be a full, clear, and exactdescription of the same,reference being had to the accompanyingdrawings, forming part of this specification, in which- Figures'l and 2are views of the ferrule of my improved cant-hook, showing it indifferent positions. Fig. 3 is a sectional view of the same, taken onthe line 00 00, Fig. 2. Figs. 4, 5, and 6 are views showing differentforms of the rib which goes around the inside of theferrule.

Similar letters of reference in the several figures denote the sameparts.

My invention relates to improvements in cant-hooks; and it consists inthe novel construction of the ferrule, whereby the same is enabled. tobe more securely attached ,to and prevented from rotation upon thehandle or staff, substantially as I will now proceed to describe.

In the drawings, A represents the handle, B the ferrule, and O the pikeor point.

The ferrule is preferably made of annealed cast steel or iron. It ispreferably of tapering form, as shown. On one side it is provided withprojecting lugs or cars a a, between which the book of the implement isadapted to be pivoted by means of a cross-bolt, b, passing laterallythrough said lugs and secured by a screwnut, c. Washers b b are mountedupon the bolt on each side of the hook and between the lugs, and when itis desired to tighten the ferrule one or more of such washers can beremoved.

The body of the ferrule is divided or opened from its larger end downthrough between the lugs to a point, d, as shown, which constructionenables the ferrule to be contracted by means of the nut and bolt, so asto cause it to bind tightly upon the staff, and thus compensate for anyshrinkage of the wood, &c.

Shoulders or stops 0 and f are provided at the top and bottom of thelugs for the purpose of limiting the throw of the hook.

N ear its smaller end the ferrule is provided with a series of internalprojecting ribs or threads, g, which are preferably made taperhectionwith the short press,

ing and given a slight spiral twist, and terminate rather abruptly, soas to form shoulders g, as shown. These ribs assist materially in bolding the ferrule upon the handle. Near its upper end, at the point wherethe greatest strain is applied, tending to rotate it-narnely, justopposite the lugs which hold the hook-the ferrule is provided with twoadditional shorter ribs, hh. These ribs not onlyassist in holding theferrule on, but prevent its rotation.

Extending around the inside of the ferrule, just below the ribs h h, isa rib, r3, shaped in cross-section, as shown in Fig. 4:, and dividedinto several sections, the ends of which are prominent and well definedand assist in preventing the rotation of the ferrule on the handle. Thisrib may or may not be used in conlongitudinal ribs h h, or it may beused exclusively and the longitudinal ribs omitted, as desired. It may,when used, also be made in the form shown inFigs. 5 and 6.

As the shrinkage of the handle can never equal twice the projection ofthe internal ribs, it is evident that the ferrule can neither rotate nordrop off.

The smaller end of the ferrule is preferably slightly enlarged on theinside, to allow of the driving in of wedges to expand the end of thehandle and hold the latter more securely.

In attaching the pike or point to the handle of a cant-hook it hasheretofore been customary to bore a hole in the handle-and burn the holeto shape it to the required taper to correspond to the taper of thepike; but this burning or charring weakens the handle ata point wherestrength is of the greatest importance. I now propose to bore the holein the handle,

. then coat the shank of the pike with oil-paint,

and force it into the hole to its seat with a powerful press. The fullstrength of the wood is thus preserved, and water is notpermittedto getinto the hole and act injuriously, as at present.

In applying the ferrule to the staff or handle I first coat its insideor the end portion of the handle with oil-paint, and then, with apowerset it in place. The employment of the oil-paintin this connectionalso, in a great measure, prevents saturation of the wood with water,and shrinkage. v

The ferrule may be heated and shrunk to its thereby removes theprincipal cause of 10 place upon the handle; but I prefer to employ thepaint and press.

I claim as my invention- 1. The combination of a divided ferrule hav- 5ing internal for drawing and causing the staff, substantially as 2. Thefe projecting ribs with a nut and bolt the parts of the ferrule togetherits ribs to embed into the wood of described.

rrnle ha ving the longitudinal ribs 9 g at its lower end, the shorterribs h h oppo- :0 site the hook-supporting lugs, and the internal rib,1', extending around the ferrule below the ribs h h, substantially asdescribed.
